| 摘要 |
The present invention relates to an arrangement at transmission of a number of signals each having a frequency component, between a base station unit and an antenna arrangement having a number of radiation element. The base station unit includes a combiner unit in which signals containing a frequency component are combined to a multi-frequency signal which is transmitted to the antenna arrangement (20). This includes a power dividing unit (3) in which the multi-frequency signal is divided into a number of, preferably similar multi-frequency subsignals ( phi l,..., phi n) and a number of controllable filter arrangements (4l,...,4n) for extracting a number of signals essentially consisting of a frequency from multi-frequency subsignals. Moreover, the antenna arrangement includes a number of amplification devices (5l,...,5n), in which single-frequency signals are amplified for feeding to a number of radiation elements (6l,...,6n). <IMAGE> |
